SPECIFICATION forming part of Letters Iatent No. 310,525, dated January 6, 1885.

Application filed June 2T, 1884. (No model.)

To LZZ whom it may concern:

Be it known that I, ELEAZER KEMPsHALL, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in ButtonSetti n g Instruments, of which the following is a specification.

My invention relates to an improvement io upon the button-setting instrument patented to me May 20, 1884, No. 298,984.

In the accompanying drawings, Figure l is a side elevation of my improved button-set ting instrument. Fig. 2 is a transverse section of parts thereof on line .r x of Fig. l. Fig. 3 is a transverse section of parts thereof', together with a plan view of the lower jaw. Fig. 4 is a longitudinal section of said lower jaw on line if y of Fig. 3, and Fig. 5 is a side 2o elevation of the lower jaw, with the side gage represented as broken away and removed in order to better show the other parts.

rihe four last figures are on an enlarged scale. The upper jaw or member, A, may be of any 2 5 ordinary character.

The changes which I make in iny present improvement are found upon' the lower jaw, I. I still retain the yielding guide-block a, slotted longitudinally, the anvil Z1, and the 3o holding-spring c within the slot of said guideblock. Instead of slotting the guideblock through from side to side, I leave a solid wall or connection upon one side, as shown at (l, which wall answers as a stop or gage against which one end of the head bar or base ol" the fastener may rest in locati ng its position in the instrument.

rflic broken lines in Fig. 2 indicate one ol my fasteners as properly located wit-,hin the 4o setting-instrument.

Instead of supporting the anvil Z) within the Iiaw B Iupon both sides of the yielding block, I support it only upon one side, and I prefer to form it in the form of an angle-iron with one wing secured to the side of jaw I3, while the other, which forms the anvil proper, terminates within said slot, as shown most clearly in Figs. 2, 3, and 5.

For cheaply securing the holding-spring c 5o in place,Islot the yielding guide-block through from end to end, as shown, and then remove `them toward the upper jaw.

a portion of the metal at each end upon one side of said slot, so that the spring may be secured after insertion by bending its ends over the ends of the block upon that side, as shown in Fig. et.

C designates a spring, which rests upon the end at the longer side of the guide-block, as shown in Eig. Li, for holding the guide-block in the position represented when not dis- 6o placed by other force. Upon one side of this spring C, I form a wing or guide, j", which eX- tends up by one end ofthe anvil, so as to support one end of the head bar or base of my fastener when it is seated in place, as shown in Fi g. 2. By reference to said figure it will be seen that the fastener is'securely held in its place within the guideblock by means of the spring C and opposing wall of the guide-block acting upon the two flat sides of the fastener, 7o and by the solid wall d of the yielding block aand the guide ,f on the yielding spring C, acting, respectively, against the two ends of the base or head. All of these guides except the anvil yield, so as to be out of way of the central prong or hook ofthe fastener as the operation of bending it progresses.

The spring C, with the wing or guidef, may be used in connection with the instrument shown and described in the patent hereinbe- Se fore nalned, and without any ofthe other improvements herein described, and when so used will be considered as of my invention.

I am aware that a prior patent shows an instrument for setting buttons by means of a staple forni of `fastener, which instrument has two movable pistons constructed to work in guideways formed in the lower jaw, the ends of which pistons act under the inliuence of a lever upon the ends of the wire staple to press go Such an instrument is hereby diselaimed. The pistons in said instrument do not yield away from the companion jaw as the jaws are brought together, and consequently they are not yield-A ing guides in the sense of that term as used by me.

I claim as my inventiond l. In a buttonsetting instrument, the combination of the slotted guide-block having the ioe solid wall d extending along one sideof the slot thereof, and the anvil Zi, secured to the jaw B, and terminating within the slot, substantially as described.

2. In a button-setting instrument, the conibination of the yielding guide-block, slotted longitudinally from end to end, the anvil b,pro jecting into said slot, and the spring c, extending longitudinallythrough the slot bythe side of the anvil, and with its ends bent to one side, substantially as described.

3. In a button-setting instrument, the eombination of an anvil, a yielding guide-block slotted longitudinally, and the spring C, for pressing upon the end of the guide-bloek,a nd
